[0001] COIL REBAR STRAIGHTENING AND BENDING MACHINE [0002]

The present invention relates to a calibration and bending cutter for a coil reinforcement, and more particularly, to a coil reinforcement that can be used as a straight reinforcement without any further correcting operation by straightening the coil (roll) reinforcement in all directions, It is possible to improve the calibration efficiency of the coil reinforcement by pre-calibrating and steadily supplying it before the bending and cutting process of the coil reinforcement so as not to cause the vibration from the end portion of the coil reinforcement passing through the bending portion and the cut portion to the bending portion and the cut portion And more particularly to a calibrating and bending cutting machine for a coil reinforcement.

Rebar is a reinforcing bar used for various civil engineering structures of reinforced concrete. It is divided into a straight reinforcing bar and a coil (roll) type reinforcing bar according to the manufacturing type.

In recent years, production of coil-type reinforcing bars has been increasing in consideration of productivity and logistics.

On the other hand, since the coil-shaped reinforcing bars are wound in a coil shape by an arbitrary curvature, straightening and bending and cutting are required depending on the purpose of use of the reinforcing bars.

Since the present invention relates to a processing apparatus for a coil reinforcement, only this will be described.

Patent Document 10-1051122 discloses a reinforcing bar automatic feeding apparatus for automatically conveying, bending and cutting reinforcing bars, comprising: a reinforcing bar providing reinforcing bars in a roll form; A reinforcing bridge for straightening the reinforcing bars supplied from the reinforcing bars; A position adjusting unit for fixing the reinforcing bars of the plurality of strands simultaneously passed through the reinforcing bar correcting unit at a programmed position; A bending rod that is located adjacent to the position adjusting unit and that bends the reinforcing bars fixed by the position adjusting unit from the end, the centering roller rotating about the centering roller, and the distance adjusting unit A reinforcing bending portion including a bending roller that is mounted as far as possible; And a cutting unit which is located adjacent to the position adjusting unit and simultaneously cuts the plurality of strands of the reinforcing bars bent by the reinforcing bars bending portion. The automatic reinforcing bar machining apparatus automatically draws the reinforcing bars from the reinforcing bars provided in the form of rolls The effect of straightening is weak because the steel reinforcing bars are pressed only at the upper and lower sides of the steel reinforcing bars. In other words, the upper and lower straightening can be performed. However, it is impossible to correct the horizontal straightening, , It is troublesome to always supply the reinforcing bars in accordance with the direction of the reinforcing steel bridge, and since the reinforcing bars have curvature before the correction, it is very difficult to supply the reinforcing bars so that they are bent upward and downward.

In addition, since the ends of the coil are extended to the bridge while expanding the coil reinforcement, it is very difficult to supply the coil reinforcement because the coil reinforcement is before the calibration.

In addition, since there is no structure for supporting the reinforcing bar passing through the bending portion during the bending and cutting process of the coil reinforcement, the coiling of the coil reinforcement is severe, and the longer the working length of the coil reinforcing bar becomes, Malfunction of cutting and the cutting surface of the coil reinforcing bar do not maintain a uniform surface.

The fixing metal bracket 61 supports the reinforcing bars not only when cutting the reinforcing bars but also when bending the reinforcing bars.

The present invention is configured to process one reinforcing bar and two or more reinforcing bars together, and the above-mentioned rollers are provided with one or more substantially semicircular grooves in which reinforcing bars are inserted into the outer circumferential surface.

In the present invention, it is necessary for the operator to transfer the coil reinforcing bars stored in the reinforcing steel supplying portion to the first correcting portion 20 before the reinforcing bars are supplied to the first correcting portion 20, In order to solve this problem, as shown in FIGS. 7 and 8, a reinforcing bar pre-calibrator 70 may be applied to the entrance side of the reinforcing bars in front of the primary orthogonal section 20.

The free calibrating device 70 includes a body 71 which is removably assembled in front of the support 21 of the primary calibrator 20 through a fastener such as a bolt or a clamp and is accommodated in the body 71, And a presser 72 for rectifying and straightening the reinforcing bar.

The body 71 should basically be open on both sides along the direction of the reinforcing bars and be an area that can be firmly fixed to the primary bridge 21, Is a 'c' shaped block that is open.

The body 71 is provided with, for example, a semicircular seating groove 71a in which a reinforcing bar is seated on one side of the inside thereof.

The pressurizer 72 includes a hydraulic jack 74 fixed to the body 71 through a fixing bracket 73 and a hydraulic jack 74 disposed to face the surface having the seating groove 71a in the body 71, And a pressure plate 75 that presses the reinforcing bar while being moved by the hydraulic jack 74.

[

The present invention is configured so that the first order orthogonal section 20 can be used only when necessary. This is because the second order orthogonal section 40 does not use the first order orthogonal section 20 according to the curvature, And in this case, there is no meaning in the use of the primary calibration unit 20 and only the inconvenience is weighted.

9, the support base 21 of the primary calibration unit 20 is assembled such that one side of the support base 21 is foldably connected to the cabinet 10 through a hinge 27, and the cabinet 10 is fixed to the cabinet 10 through an inclined brace 28. [ .

[

Further, the present invention is characterized in that the reinforcing bars are prevented from being shaken during the bending and cutting processes of the reinforcing bars to give a feeling of bending and cutting.

The conventional reinforcing bending machine has no structure for supporting the reinforcing bars passing through the bending roller, so that the reinforcing bars of the portions passing through the bending roller during the bending and cutting of the reinforcing bars are severely shaken. In the present invention, An alignment member 80 for supporting the reinforcing bar 1 passed through the portion 50 at the upper portion (or lower portion) to reduce the shaking of the reinforcing bar is applied. Since the reinforcing bars formed by the bending portions 50 are bent in a clockwise or counterclockwise direction, it is possible to apply the aligning members 80 to the upper or lower portions of the reinforcing bars.

The aligning member 80 is preferably composed of at least one aligning roller, preferably two or more aligning rollers 81, rotated by the rebar 1 in order to minimize the frictional force with the rebar 1.

The aligning roller 81 is detachably assembled (such as a fastener) to the cabinet 10 via the roller bracket 82.

Also, considering that the diameter of the reinforcing bars is variable, the alignment bracket 82 is configured to be adjustable in height. For example, a multi-step height adjusting groove (or hole) may be formed in the cabinet 10 and a roller bracket 82 may be selectively assembled to the height adjusting groove.

The function of the coil reinforcement and the bending cutter according to the present invention is as follows.

1. Reinforcement data input

The operator inputs bending data (bending angle, bending position, bending number, etc.) and cutting data (cutting position) using the input pad. Since the present invention is capable of both cutting after bending and cutting in a straight line, data suitable for machining can be input. Further, the distance between the monogastric portion 20, the feeding portion 30, and the secondary calibration portion 40 is adjusted according to the diameter of the reinforcing bar.

2. Reinforcement supply.

The coil wound around the reinforcing feed portion is pulled and pulled out, and the end portion is inserted into the inlet of the primary processing portion 20. [

In the case where the free calibrating machine 70 is applied, the operator opens the presser 72 of the free calibrating machine 70 from the body 71 to secure a clearance space therebetween and presses the reinforcing bar between the body 71 and the pressing plate 75 of the presser 72 And the pressure plate 75 is moved through the hydraulic jack 74 to pressurize the reinforcing bar.

3. Primary calibration.

When the operator manually pushes the reinforcing bars, the reinforcing bars are straightened while passing between the pinch roller 22 and the correcting roller 23 of the primary correcting unit 20.

The reinforcing bars exiting the primary guide tube 31 are fed by the primary feeding roller 32 and the primary feeding pinch roller 33 of the primary feeding section.

After passing through the primary feeding part, the reinforcing bar passes through the secondary guide pipe 34 and is fed to the secondary feeding part without departing from the path.

The reinforcing bar is fed by the rotational force of the secondary feeding roller 32 of the secondary feeding part and the primary feeding pinch roller 33, and then fed to the bending part 50 while passing through the tertiary guide pipe 37.

5. Second calibration.

The reinforcing bars are supplied to the secondary calibration section 40 by the rotational force of the feeding section 30. [

The reinforcing bar is rectilinearized while passing between the pinch roller 42 and the straightening roller 43 of the secondary correcting unit 40.

6. Bending.

The feed motor for driving the primary and secondary feeding rollers 32 and 35 of the feeding unit 30 is operated and stopped under the control of the controller and the controller sets the value inputted in the above-described 1. reinforcement data input step Controls the operation and stop of the feeding motor on the basis of which the reinforcing bar stops at the bending position.

The bending roller 52 of the bending portion 50 rotates to bend the reinforcing bar with the stop of the reinforcing bar.

The bending of the reinforcing bar is made one or more times depending on the shape, and the bending of the reinforcement can be performed twice or more as described above through the control of the controller based on the input value.

7. Cutting.

Through the control of the controller, the reinforcing bars stop at the cutting position, and at the same time, the cutter 62 of the cutting portion 60 cuts the reinforcing bars.

If the rebar is to be cut straight without bending, the above-mentioned 6. bending process is performed. 7. The cutting process proceeds to cut the straightened reinforcing bars to a certain length.
